Frequently Asked Questions - AFE-E420 Advantech

How do I install the operating system on the AFE-E420?

Insert a bootable USB drive with your OS (e.g., Windows 10 or Ubuntu), then power on the device. Press F2 or DEL during startup to enter BIOS. In the Boot menu, set the USB drive as the first boot device. Save and exit. Follow the on-screen instructions to complete the installation. Drivers can be downloaded from the Advantech support website.

What is the maximum RAM capacity of the AFE-E420?

The AFE-E420 supports up to 32 GB DDR4 memory via two SO-DIMM slots. Use compatible 1.2V DDR4 modules for optimal performance.

Can I use the AFE-E420 with 24V industrial power supplies?

No, the AFE-E420 requires a 12V DC power input (range: 10.8V to 13.2V). Using a 24V supply may damage the device. Use the provided power adapter or a regulated 12V PSU.

How do I connect a serial device to the AFE-E420?

The AFE-E420 has two RS-232 COM ports (DB9 male). Use a standard serial cable to connect your device. For RS-422/485, you may need an adapter. Configure the port settings (baud rate, parity, etc.) in your operating system.

Does the AFE-E420 support 4G LTE connectivity?

Yes, the AFE-E420 has one M.2 2230 Key E slot that can accommodate a 4G LTE module. Additionally, a mini-PCIe slot is available. You will need to install the appropriate module and antenna (not included). Ensure drivers are installed.

What is the operating temperature range of the AFE-E420?

The device is designed for fanless operation and can operate from -20°C to 60°C. For extended lifespan, avoid prolonged exposure to temperatures near the upper limit.

How do I reset the BIOS password on the AFE-E420?

To reset the BIOS password, clear the CMOS by removing the internal battery (CR2032) for 1 minute, then reinsert it. Alternatively, locate the CMOS jumper on the motherboard and short it for 10 seconds. This will reset all BIOS settings to default.

What type of storage does the AFE-E420 support?

The AFE-E420 supports M.2 SATA SSD (M key, 2280 form factor) and one 2.5-inch SATA HDD/SSD (sold separately). The included storage is a 128 GB M.2 SATA SSD.

Is the AFE-E420 wall-mountable?

Yes, the AFE-E420 has mounting holes on the bottom (VESA 75x75 or 100x100). A mounting bracket kit is included. Ensure the surface can support the device weight (2 kg).

How do I update the BIOS on the AFE-E420?

Download the latest BIOS file from the Advantech support page for the AFE-E420. Copy it to a FAT32 USB drive. Enter BIOS (F2 on startup) and use the 'EZ Flash' utility to update. Do not interrupt power during the process.

3.4 Jumpers & Switches

You may configure your card to match the needs of your application by setting jumpers. A jumper is a metal bridge used to close an electric circuit. It consists of two metal pins and a small metal clip (often protected by a plastic cover) that slides over the pins to connect them. To "close" a jumper, you connect the pins with the clip. To "open" a jumper, you remove the clip. Sometimes a jumper will have three pins, labeled 1, 2 and 3. In this case you would connect either pins 1 and 2, or 2 and 3.

The jumper settings are schematically depicted in this manual as follows:

A pair of needle-nose pliers may be helpful when working with jumpers. If you have any doubts about the best hardware configuration for your application, contact your local distributor or sales representative before you make any changes. Generally, you simply need a standard cable to make most connections.

4.2.4 eMMC

Write/Read/Verify data

4.2.5 RS-232

COM-A:

Verify according to the debug port method.

COM-B:

MODE0 = 457, MODE1 = 456, DEV = /dev/ttyLP3

COM-C:

MODE0 = 499, MODE1 = 500, DEV = /dev/ttyUSB0

COM-D:

MODE0 = 503, MODE1 = 504, DEV = /dev/ttyUSB1

COM-E_ISO_TOP:

MODE0 = 440, MODE1 = 441, DEV = /dev/ttyUSB2

COM-F_ISO_Bottom:

MODE0 = 447, MODE1 = 446, DEV = /dev/ttyUSB3

Steps:

Config to RS-232:

\echo \{MODE0} > /sys/class/gpio/export

\echo \{MODE1} > /sys/class/gpio/export

\echo out > /sys/class/gpio/gpio\{MODE0}/direction

\echo out > /sys/class/gpio/gpio\{MODE1}/direction

\echo 1 > /sys/class/gpio/gpio\{MODE0}/value

\echo 0 > /sys/class/gpio/gpio\{MODE1}/value

Test Command:

\stty -F \{DEV} -echo -onlcr 115200

\cat \{DEV} &

\echo "Serial Port Test" > \{DEV}

4.2.6 RS-485/422

COM-A:

MODE0 = 4 5 3, MODE1 = 4 5 2, DEV = / dev / ttyLP0

This port is used as a debug console, so the following additional steps are required before testing RS-485/RS-422.

1. Change debug port from COM-A to COM-B:
   (U-Boot Console)
   \$ setenv console "ttyLP3,115200 earlycon"; saveenv
   (Linux Kernel)
   \$ systemctl enable [e-mail]
   \$ systemctl disable [e-mail]
   \$ systemctl stop [e-mail]

2. System reboot.

3. Follow normal RS-485/422 test method like COM-B to F.

4. Recovery system

(Linux Kernel)

\$ systemctl enable [e-mail]

\$ systemctl disable [e-mail]

\$ systemctl stop [e-mail]

(U-Boot Console)

\$ env default -a; saveenv

COM-B:

MODE0 = 4 5 7, MODE1 = 4 5 6, DEV = / dev / ttyLP3

COM-C:

MODE0 = 4 9 9, MODE1 = 5 0 0, DEV = / dev/ttyUSB0

COM-D:

MODE0 = 5 0 3, MODE1 = 5 0 4, DEV = / dev / ttyUSB1

COM-E_ISO_TOP:

MODE0 = 4 4 0, MODE1 = 4 4 1, DEV = / dev / ttyUSB2

COM-F_ISO_Bottom:

MODE0 = 4 4 7, MODE1 = 4 4 6, DEV = / dev/ttyUSB3

Steps:

Change MODE0/MODE1 to switch mode, (01: 485, 11: 422)

Config to RS-485:

\echo \{MODE0} > /sys/class/gpio/export

\echo \{MODE1} > /sys/class/gpio/export

\echo out > /sys/class/gpio/gpio\{MODE0}/direction

\echo out > /sys/class/gpio/gpio\{MODE1}/direction

\echo 0 > /sys/class/gpio/gpio\{MODE0}/value

\echo 1 > /sys/class/gpio/gpio\{MODE1}/value

Config to RS-422:

\echo \{MODE0} > /sys/class/gpio/export

\echo \{MODE1} > /sys/class/gpio/export

\echo out > /sys/class/gpio/gpio\{MODE0}/direction

\echo out > /sys/class/gpio/gpio\{MODE1}/direction

\echo 1 > /sys/class/gpio/gpio\{MODE0}/value

\echo 1 > /sys/class/gpio/gpio\{MODE1}/value

Setup RS-485 wiring:

Adam-4520. Adam-4520 Pin Data- and Pin Data+ connect to DB9 Pin1 and Pin 2

Setup RS-422 wiring:

Adam-4520. Adam-4520 RX- <-->DB9 Pin 1, Adam-4520 RX+ <-->DB9 Pin 2, Adam-4520 TX- <-->DB9 Pin 4, Adam-4520 TX+ <-->DB9 Pin 3

Remember to set up RS-485/422 before test.
